The invention discloses a longitudinal bidirectional taper clutch self-adaptive speed change manual front and back gear shifting electric drive system which comprises a motor and a speed change assembly, and the speed change assembly comprises a main shaft, a self-adaptive cam clutch mechanism, a manual front and back gear shifting mechanism and a speed reducing mechanism. The reverse gear function is achieved, longitudinal arrangement is achieved, meanwhile, the end face cam boss is integrally formed on the main shaft, the structural strength is high, and reliability is good. The self-adaptive mechanical transmission has the advantage of self-adaptive mechanical transmission, switching and maintaining of a low-speed gear and a high-speed gear are achieved under the combined action of traction force and running resistance, high driving torque can be provided in a constant torque area, and high rotating speed can be provided in a constant power area. And low-speed, large-torque and high-efficiency requirements of various complex working conditions of vehicle acceleration, climbing and high-speed driving can be met. And more preferably, the optimal working opportunity for optimizing the power of the motor can be selected, the power output efficiency of the driving motor is improved, the economical efficiency is greatly improved, and the continuous acceleration performance is enhanced.
